The unique design of the cutter drum – with six shafts and heavy duty cutters – means that the SPE BEF 275 Multiplane Scarifier can be used for both preparation and heavy duty planing work. In common with most other machines of this type, the rotation of the SPE BEF 275 Multiplane Scarifier drum allows for cutting on a ‘downward motion’ where some of the cutting energy is used to propel the machine forward.
